1 whereby it is firmly seated and retained in place and serves as apivotal connection for the axletree and bolster. and straps 23constitute a fifth-wheel whereby the axletree may be connected to thebolster bythe king-bolt. A plurality of eyebol ts 2-5in this instancefour in numberare mounted horizontally through the axletree 22, and arod 26 is mounted ri idly yet detachably through the eyes of said isprovided and is constructed with plates 28 on opposite sides of its rearend portion and braces or hounds 29, fixed to and divergin from its rearend portion, and said plates an are pivoted by means of said apertureson the rod 26, the hounds confined by contact with the inner surfaces ofthe outer eyebolts and the plates confined by contact with the innersurfaces of the inner eyebolts. An axle 30 is mounted on the lower faceof the axletree 12 and is secured thereto by hook-bolts 3 1 near its endportions and by the king-bolt 24, extending through its center. Spindlesof. usual form are constructed on or attached to end portions of theaxle 30, and supporting-wheels port the forward end portion of themachine. Journal bearings 34 35 and 36 37 are mounted on, fixed to, andarched downwardly of the bed-frame and the seats or bearings thereof arein alinement across the machine. An axle member 38 is mounted forrotation in the journal-bearings 34 35, and an axle member 39 is mountedfor rotation in the journal-bearings 36 37 in'alinement with the axlemember 38. Collars 4O 41 are mounted on and fixed to the axle members 3839, respectively, adjacent the inner faces of the journal-bearings 34 37and serve to limit longitudinal movement of said axle members.Supporting traction-wheels 42 43 are mounted rigidly on the outer endportions of the axle members 38 39, respectively, and support the rearend portion of the machine as well as provide the motive power for themechanism hereinafter described. The inner end portions of the axlemembers-.38 39 abut each other in the median line of the machine withinthe hub of a gear-wheel 44, but are not connected with each other orwith said gear-wheel directly. Clutch members are formed on opposite endportions of the hub of the gear-wheel 44, and clutch mem- 32 33 arerevolubly mounted thereon and sup- The rings 19 21 olts 1n front of saidaxletree. Atongue or pole 27 hounds are apertured at their rear ends andl from side bars 10 11, and the cross-bars 14-15 IIC - bers 45 46 aremounted on and feathered for sliding movement relative to theinner endortions of the axle members-38 39 and are old normally in en agementwith the clutch members on the hu of the wheel 44 by expansive co l-springs 47 48, interposed between them and the journal-bearings 35 36.It is the function of the clutch members 45 46, either separately orconjunctively, to transmit rotary motion of the axle members 38 39 tothe gear-wheel 44 for the purpose of driving mechanism hereinafterdescribed at times, and provision is made for holding said clutchmembers out of engagement, as follows: Yoke-arms 49 50 are pivotedattheir forward end portions on a bolt 51, seated in the central portionof the cross-bar 13. Yokes are formed on the rear end portions of thearms 49 50 and engage in annular grooves in the clutch members 45 46.Toggle-levers 52 53 are pivoted at their outer ends to the centers oftheuyoke-arms 49 50, and at-the1r inner ends said toggle-levers areconjunctively pivoted to the rear end portion of an actuating-bar 54.The actuating-bar 54 extends forward within the bed-frame from its po ntof attachment to the toggle-levers to a point beneath a foot-board-55,fixed to and projecting forward from said bedframe. A crank-shaft 56 isjournaled in bearings 57, fixed to the lower end portion of thefootboard 55, and is provided with a crank 58 on one end portion, whichcrank is outturned at its extremity and extends through a slot 59 in theforward end portion of the draft-bar 54 and is secured by a nut 60. Alever-arm 61 on the crank-shaft 56 extends through a slot 62 in thefoot-board and is adapted for manual actuation to move the draft-bar 54in either direction positively. The ordinaryfunction or the lever-arm61is to manipulate the clutch members 45 46 into engagement with theclutch on the hub of the gearwheel 44, and when so engaged sa d leverarmis retained by contact with a hook 63 on a bell-crank lever 64,fulcrumed on a seatbar 65, which seat bar crosses and is fixed to thetop of the forward ends of side boards, hereinafter described. Aretractile coil-spring 66 is fixed to the bolster 12 and to the crank 58and tends to move the draft-bar 54 rearward and disengage the clutchmembers 45 46 from the hub of the wheel 44. An angle-iron 67 is fixed tothe forward edge of the seat-bar and tends to hold the handlelever 61against lateral movement out of the hook 63.

J ournal-bearings 68 69 are mounted on the cross-bars 15 16 and the sidebar 11, respectively, of the bed-frame, and a counter-shaft 70 ismounted for rotation in said journalbearings and projects at one endoutside said bedframe. A pinion 71 is mounted rigidly on thecounter-shaft 70 between its journalbearings and meshes with thegear-wheel 44,

yokes.

and collars 72 limit and prevent longitudinal movement of saidcounter-shaft.

Track-b ars 73 74 are mounted on and spaced apart from the innersurfaces of the side bars 10 11 of the bed-frame, and rollers 75 arearranged in series in the space between said track-bars and side barsand project above the upper margin of the track-bars. It is the functionof the rollers 75 to form a frictionless bed and support for thefertilizer-apron about to be described. The fertilizer-apron is formedof an angular head-piece 76, which head-piece has a bottom and frontplate rigidly connected and secured together by braces 7 7 and slats 78,arranged parallel to each other and parallel to the head-piece andsuitably connected. I have illustrated cables 79 80, arranged parallelwith each other, fixed at their forward ends to the head-piece 76,crossing beneath said head-piece and the end ortions of the intermediateslats 78, and xed rigidly at their rear end portions to the rearmostslat, (indicated by the numeral 81.) Intermediate of its ends each cable79 80 is secured to the slats and head-piece by hook-bolts 82, extendingthrou h said slats or head-piece, embracing the cables in their hooks,and secured at their upper ends by nuts 83, engaging the upper surfacesof the slats or head-piece. Through the employment of the cablesconstructed as described to connect the head-piece and various slats Iam enabled to produce an apron which may be flexed repeatedly and at thesame time provide maximum strength in resisting draft and 'erks in theoperation of the machine.

Side boards 84 85 are mounted on, fixed to, and rise from the side bars1O 11 of the bedframe. The rear end portions of the side boards 84 85are bifurcated, and yoke-bars 86 87 are mounted across the bifurcationsthereof. The yoke-bars 86 87 are of identical construction, and eachconsists of circular yokes formed with aliningstems extending inoppositedirections, the upper stem confined by an angle-plate 88 on theupper portion of a side board and the lower stem extending through therear end portion of the side bars 10 11 and arranged for verticaladjustment by means of nuts 89 90 above and below said side bars.Adjusting-screws 9192 are mounted radially of the circular yokes and areadapted to engage, center, and support journal-bearings 93 94 withinsaid A rake-shaft 95 is mounted for rotation in the journal-bearings 9394, and circular rake-heads 96 97 are mounted rigidly on said shaft andare connected by and support rake-bars 98, which rake-bars extend acrossthe machine and are provided with rake-teeth 99, arranged in staggeredrelation thereon.

A sprocket-wheel 100 on the shaft 70 is connected by a sprocket-chain101 to a sprocket-wheel 102 on one end portion of the rake-shaft 95. Adrum-shaft 103 is journaled in bearings at the rear end portions of sidebars 10 11, and a drum 104 is mounted loosely thereon between saidbearings. A clutch member is formed on one end portion of the drum 104and mates at times with a clutch member 105, feathered on the shaft'103. A cable 106 is fixed at one end to the drum 104 and is adapted tobe wound thereon, and the 0 posite end of said cable is fixed to thelower ace of the central portion of the head-piece 76. A bell-cranklever 107 is fulcrumed on the upper face of the cross-bar 16, and theshorter arm of said lever en 'ages in an annular groove in the clutchmem er 105. The longer arm of the bell-crank lever 107 is connected by arod 108 to one end of a pedallever 109, which pedal lever is mountedthrough the slot in the foot-board and is j ournaled for pedaloscillation. A retractile coil-spring 110 connects the free end of thebell-crank lever 107 to the cross-bar 15 and applies a strain to saidlever, which tends to ho ds the clutch member 105 in engagement with theclutch member of the drum 104. A lug 111 is mounted on the forward faceof the cross-bar 16 and tends to limit and determine oscillation of thebell-crank lever 107 in opposition to the resilience of the spring 1 10.

A drum-shaft 112 is mounted for rotation in bearin s fixed to theforward end portions of the si e bars 10 11 of the bed-frame. A cable113 is fixed at one end to and normally is wound on a drum 114, fixed tothe drum shaft 112, and the opposite end portion of said cable is fixedto the central portion of the bottom of the head-piece 76. This cable113 is shown in Fig. 7. A cable 115 is fixed at one end to the rearmostslat 81 of the fertilizer-aprcn and extends forward beneath the machineand is fixed to the drum 114 and is adapted to be wound on said drumoppositely to the cable 113. A skeleton casing or frame 116 is fixed toand depends from the cross-bars 14 16 or the journal-bearings attachedthereto and protects the gear-wheel 44 and pinion 71 from the entanglingengagement with the cable 115. Cables 117 118 are fixed at their forwardends to the drumshaft' 112 and are adapted to be wound on saiddrum-shaft oppositely to the cable 1.13.

The rear end portions of the cables 117 118 are attached to the forwardend portions-of retractile coil-springs 119 120, and the rear endportions of said springs are attached to end portions of the cross-bar16 of the frame.

A sleeve 121 is feathered on one end portion of the rake-shaft 95, and afriction-wheel 122 or brush-wheel is mounted rigidly on said sleeve. Abell-crank lever 123 is fulcrumed on a bracket 124, fixed to the sideboard 84 and is formed with a yoke on its rear end, engaging in anannular groove in the sleeve 121. The shorter arm of the bellcrank lever123 is connected by a rod 124* to a hand-lever 125, pivoted on theforward end portion of the side board 84. A segmental rack 126 is fixedto the side board 84, and a detent 127, slidingly mounted on the lever125, engages saidrack. The detent 127 is provided With integral. wings128 129, leading in opposite directions therefrom and folded around andslidin ly engaging the lever 125, and the upper en portion 0 the detentextends through an car 130 on the lever and is provided with an eyeconnected by'a rod 131 to a tripping-lever 132, mounted on the upper endportion of the hand-lever and adaptedfor manual compression thereto. Anexpansive coil-spring 133 is interposed between the wings on the detent127 and the ear 130 and surrounds the upper portion of the detent andtends to depress the detent normally into engagement with the rack 126.It is the function of the hand-lever 132 to oscillate the bellcranklever 123 and move the sleeve 121 and brush-wheel 122 longitudinally ofthe shaft 95. A bracket 134 is'mounted on and projects laterally fromthe rear end portion of the side board 84, and a counter-shaft 135 ismounted for rotation in a journal-bearing on said bracket. A disk 136 ismounted rigidly on one end portion of the counter-shaft at right anglesto the brush-wheel 122, and the upper surface of said disk is adapted tobe engaged by 9 5 said brush-wheel. Any adjustment of the brush-wheellongitudinally of the shaft 95 moves said brush-wheel radially of thedisk 136 and changes the speed at which said disk is rotated by thebrush-wheel. Abevel-gear 137 is mounted rigidly on the lower end portionof the counter-shaft'135 and meshes with a bevel-gear 138, rigidlymounted on a stubaxle 139, seated in a rear end portion of the side bar10 of the bed-frame. A socket 140 is mounted on the outer end portion ofthe stub-axle 139 and receives the lower end portion of thecounter-shaft 135, and an expansive coil-spring 141 is mounted on saidcounter-shaft and impinges said socket and the bevel-gear 137,respectively. Thus is provision made for longitudinal movement of thecounter-shaft 135 to compensate for vertical adjustment of therake-shaft 95 or for Wear of the brush-wheel and disk, at the same timeinsuring a yielding pressure of the disk against the brush-wheel. shaft139, however, is not sufficient to remove the gears 137 and 138 frommesh. A pinion 142 is rigidly attached to the shaft of the bevel-gear138 and meshes with a pinion 143 of materially greater diameter than thegear, which pinion is mounted rigidly on the drumshaft 103.

A bell-crank lever 144 is fulcrumed on the lower face of the crossbar13, and one arm of said lever is connected by a rod 145 to the extremityof the longer arm of the bell-crank lever 64. A retractile coil-spring146 is connected at one end to the lower margin of the This movement ofside bar 11 and at its other end to the bellcrank lever 144, and thestrain of said spring tends to hold the lever 64 in such position thatthe hook 63 thereon will engage and retain the hand-lever 61. A rod 147is slidingly mounted in a bearing 148 on the cross-bar 15, and theforward end of said rod is connected to one arm of the bell-crank lever144. A hook is formed on the rear end portion of the rod 147 andprojects upward across the rear margin of the cross-bar 15 and into thepath of travel of a loop 149, fixed to and projecting downwardly fromthe lower face of the headpiece 76.

Brackets 150 151 are fixed to and project above the forward portions ofthe side boards 84 85, and arms 152 153 are pivoted in the upper ends ofsaid brackets and project rearwardly and downwardly therefrom to pointsof attachment to opposite end portions of a clearer-bar 154. The arms152 153 are formed with lugs 155 156, projecting outward therefrom andengaging the upper margins of the side boards 84 85. Retractilecoil-springs 157 158 further connect the arms 152 153 to the brackets150 151 and tend to hold the lugs on said arms in contact with the uppermar ins of the side boards. The clearer-hea 154 is provided with teeth159, projecting rearwardly and downwardly into v spaces between theteeth 99 on the rake-bars 98 and just out of contact with said rakebars.

In practical operation of this machine the parts are assembled as shownin the drawings and above described, except that the brush-wheel 122 maybe positioned or adjusted wherever desired relative to the disk 136. Themachine then is moved across the field with the apron loaded withfertilizer. The traction-wheels 42 43 transmit rotary motion through theclutch members 45 46 to the gear-wheel 44, and said gear-wheel in turnrotates the pinion 71, counter-shaft 70, and sprocket-wheel 100. Thesprocketwheel 100, acting through the chain 101, rotates thesprocket-wheel 102 and rake-shaft 95, thus revolving the rake in thedirection of the arrow in Fig. 4. In the rotation of the rake-shaft thebrush-wheel 122 engages and rotates the disk 136, counter-shaft 135, andbevel-gear 137, and the motion of the bevel-gear is transmitted, throughthe bevelgear 138, to the spur-gear 142. The spurgear 142 rotates thepinion 143 and drumshaft 103, and since the clutch member is inengagement with the drum 104 such rotation of the drum-shaft rotates thedrum. and winds the cable 106 thereon. Since the cable 106 is attachedto the head-piece 76 of the apron, it follows that the winding of saidcable on the drum 104 draws said apron rearward. The rearward movementof the apron effects an unwinding of the cable 113 from the drum 114,and such unwinding effects a sis/55c rotation of said drum 114 and windsthe ca bles 117 118 on the shaft 112 and stretches the springs 119 120to the end of storing power in said springs. The rearward movement ofthe apron also causes the cable to travel forwardly around the drum 114and in so doing insure the forward movement of the tail end of the apronbeneath the bedframe and sustains or supports said tail end of the apronclear of the ground. When the apron has reached its rearmost limit ofmove ment, the loop 149 on the head-piece 76 engages the hook on the rod147 and moves said rod rearward a distance suflicient to oscillate thebell-crank levers 144 and 64 and release the hand-lever 61 from the hook63, whereupon said hand-lever moves forward under strain of the spring66 and effects an operation of the yoke-arms 49 5O sufficient todisengage the clutch members 45 46 from the gearwheel 44 and preventfurther operation of the mechanism by cutting off the supply oftraction-power therefrom. Further forward movement of the machine has noeffect whatever on the mechanism which moves the rake and apron. Sincethe rake rotates in the direction of the arrow in Fig. 4, it has atendency to impede the delivery of fertilizer by the apron beneath therake, the teeth 99 moving the fertilizer back and insuring the deliveryof a thin and uniform sheet of fertilizer in more or less pulverizedcondition from the apron. It sometimes occurs that portions of thefertilizer will adhere to rake-bars 98 and teeth 99, and to clear saidteeth the 100 clearer-head 154 and teeth 159 are provided, yieldinglymounted, as described, and adapted to comb the rake and clear a maximumamount of substance therefrom. The yielding mounting of the clearer-bar154 avoids I05 breaking the teeth or arms thereof or the teeth of therake when a superior resistance is met with, such as frozen fertilizeror min eral chunks carried by the rake. When the apron has been unloadedthrough the opera- 1 10 tion above described, foot-power may be appliedto depress the pedal 109 and apply draft to the rod 108 sulficient tomove the bell-crank lever 107 against the resilience of the spring 110and disengage the clutch 105 II 5 from the drum 104, whereupon theresilience of the springs 119 unwinds the cables 117 118 from thedrum-shaft 112 and in so doing rotates said drum-shaft and the drum 11 4and rewinds the cable 113 on said 120 drum. The rewinding of the cable113 on the drum 114 draws the apron into the initial position shown inthe drawings and first described, the cable 115 traveling rearwardaround the drum and at all times sustaining an apron driven by said rakein one direction, 1 0
